"The Omnibus Crime Control and Safe Streets Act of 1968 requires the Administrative Office of the United States Courts (AO) to report to Congress the number and nature of federal and state applications for orders authorizing or approving the interception of wire, oral, or electronic communications. The statute requires that specific information be provided to the AO, including the offense(s) under investigation, the location of the intercept, the cost of the surveillance, and the number of arrests, trials, and convictions that directly result from the surveillance. This report covers intercepts concluded between January 1, 1999, and December 31, 1999, and provides supplementary information on arrests and convictions resulting from intercepts concluded in prior years. From 1998 to 1999, the total number of intercepts authorized by federal and state courts increased 2 percent to 1,350, reflecting continued growth in applications involving the surveillance of drug offense operations (up 2 percent). Following a decrease of one half of one percent in 1998, the number of applications for orders by federal authorities rose 6 percent in 1999. The number of applications reported by state prosecuting officials dropped 2 percent in 1999, with fewer jurisdictions providing reports than in 1998. The number of federal intercept applications authorized has grown over the last 10 years, increasing 94 percent from 1989 to 1999, while state applications have risen 65 percent since 1989. The number of intercepts employed in drug-related investigations also has experienced significant growth. Drug offenders were targeted in 978 of the interceptions concluded in 1999, compared to 471 in 1989, a 108% increase."
